<H2>updatedisplay</H2>
<HR>
Force display update, or suspend/resume updates
<HR>

<H3>Usage:</H3>
   <BLOCKQUOTE>
      <B>updatedisplay</B> [<B>suspend</B>|<B>resume</B>] <BR><BR>
   </BLOCKQUOTE>

<H3>Summary:</H3>
   <BLOCKQUOTE>
      The <B>updatedisplay</B> command allows the display redraw to
      be suspended and resumed.  The main situation where this is
      useful is inside a script or series of commands, where it is
      not desired to have the display refresh at each step.  Areas
      needing to be redrawn will accumulate and be processed all at
      once when <B>updatedisplay resume</B> is called. <P>
 
      Calls to <B>updatedisplay suspend</B> can be nested, so that
      the display will not update until the same number of calls
      to <B>updatedisplay resume</B> have been encountered. <P>

      Without arguments, <B>updatedisplay</B> forces an immediate
      display redraw.

<H3>Implementation Notes:</H3>
   <BLOCKQUOTE>
      <B>updatedisplay</B> is implemented as a built-in window command in <B>magic</B>.
